A code-orange heat warning is currently in effect for nine provinces in the Netherlands [1].

The extreme temperatures pose significant health risks to the public, necessitating immediate preventative measures to avoid heat-related illnesses. With temperatures expected to rise above 30 °C [2], officials and experts are urging citizens to adopt specific cooling behaviors to manage the heat.

NOS weather presenter Peter Kuipers Munneke said that simple tools can provide rapid relief. He recommended using a water spray to dampen the skin, which helps the body cool down through evaporation. In addition to skin hydration, he said the public should seek shade and avoid direct exposure to the sun during peak hours.

Maintaining internal hydration is another critical component of heat safety. Munneke said staying hydrated and consuming cooling foods, such as ice cream, can help regulate body temperature. These small interventions are designed to lower the risk of heatstroke and exhaustion as the heatwave persists.

The current weather pattern has led to unprecedented nocturnal temperatures. Reports indicate the warmest night ever recorded will not drop below 26 °C [3]. This lack of nighttime cooling increases the physiological strain on the human body, as it cannot recover from the daytime heat.

While some sources have listed a code-yellow warning for the entire country, the most severe alerts remain concentrated in the nine provinces under the code-orange designation [1]. Residents in these areas are encouraged to prioritize sun protection, and utilize any available cooling methods to mitigate the effects of the rising mercury.

The issuance of a code-orange warning combined with record-breaking nighttime temperatures indicates a severe heat event that prevents the body from naturally resetting its temperature during sleep. This increase in nocturnal heat significantly elevates the risk of cardiovascular strain and heat-related mortality, particularly among elderly populations and those without air conditioning.
